I PROVED APPARATUS FOR coNnnNsINGJN DISTTLLING SPIRITS AND omen moo-ms.

The Schedule referred to in these Letters Patent and. making part of the same.

To all whom it concern Be it known that we, HENRY G; DAYTON, of Maysville, Kentucky, andJAMEs CHRISTIE, of Atlanta, Illinois, have invented a new and useful Apparatus for the Condensing of Vapor, in the Process of Distillation of Liquors, Spirits, and Liquids generally, without the use of the usual spiral metallic worm or tube, which invention is called .Dayton and Ohristies Condenser.

The nature of our invention consists in the substitution, for the ordinary worm or spiral metallic tube, used in the refrigerator-y or tub in distillation, of two or more vapor-chambers, of copper, of peculiar construction, which will give a greater number of square feet of surface for the action of cold water upon the said chambers in the processes of condensation, than can be had by the use of the worm.

To enable others skilled in the art to make and use our-invention, we will proceed to describe its use and operation. q

We construct our refrigeratory in any of the usual forms, in the centre of the top of which the neck enters, which terminates within the 'refi'igeratory in a double or two or more vapor-chambers of copper, one

. within the other, and communicating with each other by means of six copper tubes, marked in the accompanying diagram, respectively, I I I, 850., at the top, and by means of four copper tubes atthe bottom, marked, in the accompanying diagram, K K, 860.

.The exterior vapor-chamber B has a convex surface at either end. At the top it is about one-thirdlarger in diameter than at the bottom, and has about twice the space at the bottom, between the walls of itself and tub, than it has at the top, and in general shape resembles a section of conic cylinder, having a space between its lateral walls of about four or more inches.

Next, within said outer vapor-chamber, is a chamber for water or an inner refrigeratory, of the same general shape as the outer vapor-chamber, and in the diagram is marked 0; and within said inner refrigeratory is an inner vapor-chamber, D, which,-in the diagram, is cylindrical in form, having its convex surface exposed to the action of water, both at its ends and side. Theseexteriorand interior water-chambers communicate 'with each other by means of four copper tubes at thetop, marked HH.

The outer vapor-chamber, at the side near the bottom, is pierced with two tubes or pipes, marked L, for drawing off the distilled liquor, which passes through an opening in the sides, nearthe bottom of the; main tub or outer refrigeratory.

through the test-tube M, which may be ascertained by turning the cock in said test-tube, the liquor may be drawn off by means of either tubes M above mentioned.

Water is forced into the outer refrigeratory by means of a pipe, F, which enters it' at the bottom, and near the centre. The stream from this water-pipe strikes the concave surface of the outer vapor-chamber,where the distilled liquor first settles, and, as this stream is constantly flowing, the cooling of the liquor or vapor is much accelerated, and the liquor is cooled while still in the vapor-chamber, thus preserving much of its power which by the ordinary processes is lost.

By means of .a second water-pipe, E, which enters the inner water-chamber from the bottom, and near the centre, passing through the outer refrigeratory, the outer water-chamber, and the outer vapor-chamber, water is forced into, the inner water-chamber D, striking with a cold stream against the bottom of the inner vapor-chamber, where the distilled liquor first settles in this chamber, when the water is coldest, thus cooling the liquor while within the vapor-chamber, and preserving its quality and flavor. v

' It is usual to force the vapor into the condenser, in the old processes, with a high degree of heat. By the use of our process, fuel is saved at the retort, and the operation of distillation greatly accelerated.

This liquor is conducted through the pipes K K to the bottom of theouter vapor-chamber B, where it is again subjected to the cooling influence of the stream from the tube F, and is 'drawn off as above indicated.

The pipes H H, 8tc., permit the warm Water from the inner water-chamber to escape into the outer Waterchamber or tub A, and the pipe O-conducts the same away.

The particular features of the above-named invention, of the benefit of which we claim to be the first andoriginal inventors, and the benefits of which we desire to secure by Letters Patent, are the following: I

1. The alternate chambers for water and vapor,which, may be continued or repeated indefinitely, thus securing much greater surface for the action of water in cooling. 4 1

2. The concave surface of the bottom of the outer 'vap'or;chamber, which permits the fiowof water, striking it at or near the centre, to spread in every direction from the point of contact, thus cooling the entire bottom of said vapor-chamber.

3. The creation of a partial vacuum in the vaporchamber by our superior means of cooling,which causes the vapor ti'om the retort to flow promptly and readily into the vapor-chambers, substantially as described.

4. The tubes H H, I I, K K, L L, M, &c., for their various purposes and uses, in the manner substantially as set forth.
